Hi,
Please check out the below link to Ambients ACN Timecode products. These products are the direct replacement for the original Ambient products you have used I believe.

Can't think of any other TC systems that have a radio link feature but could be wrong.
Deneke, Betso and Tentacle Sync are other manufacturers of TC systems.
There are many videos online showing these different systems. You Tube.
There are many, many discussions here on JW about the different systems.

It is a well known fact (or I was under the impression it was anyway) that the foam on the mic inside a cage (Rycote) reduces the effectiveness of the cage to reduce wind noise.
My local kit supplier has told me that Rycote themselves have stated this.

Hi Masaki,
Yes I have one and use it every time I use my ms stereo schoeps ccm rig on the ccm8 channel as this mic is more sensitive to 'handling' noise. It does a great job of cutting out (attenuating) the lower frequencies.
As the filter is a steeper than that of my mixer (633) it does a better job of tempering lower frequency handling noise.
It has been available for quite a few years. I love it, it's expensive.

Maybe the battery has stayed in its protection state, I think sticking it into the charger for a kick start should bring it back to life ...... maybe. My experience was that the batteries would come back to life eventually on their own (10 mins?). Please take my observation and speculation as just that - your problem may or may not be totally different.

I've had this situation before with other types of Lithium - Hawk-Woods. What I think happens is that the start up sequence of the 664 draws too much power just for the first milliseconds (or something) and the protection circuit within the battery kicks in. I've found that initially powering the 664 from internal batteries just for the first few seconds and then switching to the lithium will not trip the battery's protection. This only happens with freshly charged Lithiums. Hope that's what up with yours.
..... or what Jordan says!
